Take a tram number 1 from outside Basel SBB in the direction of Kannenfeldplatz/Dreirosenbruecke. After 4 stops at Brausebad, change to a number 6 to Allschwil, and stay on until the end of the line. You'll need a 1-zone ticket for the journey.

A bag car will be provided, and for the benefit of late-comers the circle will be held in the usual place (Schuetzenmattpark).

On-Inn probably at the Marmaris restaurant near Brausebad.
